and is entitled
"Predominance Tag Maps"
Abstract:
A predominance map expresses the predominant data category for each
geographical entity and colors are used to differentiate a small number of
data categories. In tag maps, many data categories are present in the form
of different tags, but related tag map approaches do not account for
predominance, as tags are either displaced from their respective
geographical locations or visual clutter occurs. We propose
predominance tag
maps, a layout algorithm that accounts for predominance for arbitrary
aggregation granularities. The algorithm is able to utilize the font sizes
of the tags as visual variable and it is further configurable to implement
aggregation strategies beyond visualizing predominance. We
introduce various
measures to evaluate numerically the qualitative aspects of tag maps
regarding local predominance, global features, and layout stability and we
comparatively analyze our method to the tag map approach by Thom et al. on
the basis of real world data sets.

On behalf of Professor Scheuermann all those interested are cordially
invited to attend.
Yours sincerely,
Tom Liebmann
